PSA Nitrogen Generator

The PSA system is mainly composed of air compressors, filters, dryers, switching valve, absorber and air tanks, nitrogen tank composition. Raw materials through the air compressor pressurized air after the primary filter through into the freeze drying machine for drying, and then high into the air storage tank oil removal filter, dry, clean oil-free compressed air to go through activated carbon adsorber and then into the two only the exchange of the adsorber, the adsorber is equipped with high quality and efficiency of carbon molecular sieve, due to molecular oxygen and nitrogen molecules of different sizes, the priority in improving the molecular sieve adsorption of oxygen under pressure, some time after the zeolite adsorption of oxygen balance , according to the carbon molecular sieve adsorption at different pressures and gas adsorption on different properties, by reducing the pressure on the Elimination of oxygen molecular sieve adsorption, while another absorber boost to work, work through the alternate adsorption obtained two consecutive nitrogen flow, preparation of nitrogen through the nitrogen tank and flow meter, after passing inspection by the sampling equipment sent to the point of use after the class to use, if higher requirements may be added in subsequent purification devices for higher requirements for nitrogen.In order to improve the utilization of compressed air, reduce the impact of compressed air on the molecular sieve, improve the performance of molecular sieve, ensure the nitrogen flow continuous and stable. During the of process of design, we made a full account of the details, such as the flow of all pressure, reflux, cleaning and the buffer separating nitrogen and so on, to ensure that the gas source under the quality assurance, more efficient use and longer life of molecular.
